Markdium-JS 초보가 쓰는 async await 처음부터 이해하기
Raw
Markdium-python.py
future = excutor.submit(open, "example.txt", "r") // Non-Blocking IO로 IO 작업 시작
some_cpu_job1() // cpu 작업이 IO작업이 끝나기 전에 끝난다
some_cpu_job2() // 이 시점에서 IO 작업이 끝났다면
some_cpu_job3() // 그럼에도 불구하고 이 cpu 작업을 기다려야 한다
f = future.result() // 출력이 Blocking일 때보다 늦어진다 -> 응답성이 떨어진다
print(f.readline())
